Human case of West Nile Virus identified in Milwaukee



MILWAUKEE -- The rain may be long gone from August, but the wet weather is still taking its toll in the form of swarms of mosquitoes. The City of Milwaukee Health Department (MHD) has identified the first probable human case of West Nile Virus (WNV) this year, and there's a good chance others are infected.

“Although summer is winding down, it is important that residents remain vigilant about preventing mosquito bites,” said Commissioner of Health Jeanette Kowalik “The risk of getting WNV is present anytime that mosquitos are active.”

According to the Milwaukee Health Department, most West Nile Virus human cases in Wisconsin occur during the months of August and September. Symptoms include: fever, rash, headache and joint pain. The chances of a person contracting West Nile Virus are low and most people infected will not have any symptoms.

"There are people who get really sick. Those are the people about one in 150 who get the severe inflammation in the brain and in the spinal cord," said Angie Hagy, director of the Disease Control and Environmental Health division within the health department.

It has the potential to be deadly. Easing fears, health officials say most people who get West Nile will never know it.

"The vast majority of people who get West Nile don't develop any symptoms at all," Hagy said. "About one in 50 will actually develop symptoms and those are generally pretty mild.

Symptoms may begin between three to 15 days after being bitten by an infected mosquito. In rare cases, West Nile Virus can cause severe disease with symptoms such as muscle weakness, stiff neck, disorientation, tremors, convulsions, paralysis and coma. Older adults and people with compromised immune systems are at an increased risk of severe disease from the virus.



West Nile Virus is spread to people through the bite of an infected mosquito and is not transmitted person to person.

The Milwaukee Health Department reminds individuals to take steps to prevent mosquito bites, including:


    There is no specific treatment for West Nile virus other than to treat symptoms. If you think you have West Nile virus infection, contact your healthcare provider.
